Hi, I have jboss messaging 1.4.0 running in a jboss 4.2.1 cluster with 2 nodes. I have a clustered queue. Each node in the cluster has 2 consumers listening on this queue. Everything works fine, except occasionally a couple messages get stuck. These messages sit in the queue even if there are no other messages anywhere else in the cluster and all of the consumers are idle. Most messages received after the stuck messages get processed normally, unless they also get stuck. The only way to get them consumed is if I remove consumers from the node where they are stuck, and add new consumers.

Anyone else seen this type of behavior or know the cause? I checked the JIRA briefly and didn't see anything obvious. Thanks!

This issue hadn't been seen until we went to production (we just recently switched from tomcat/activemq to jboss/jbm), and I didn't see it in dev or qa environments... but production is running with more separate machines under higher load. I'll try to reproduce the situation in my dev environment and give instructions on how to reproduce if I'm successful. Thanks for the offer.
